Ironview Network Manager (Inm) Limitation; Acl Statistics On Fgs, Fls, And Fws Devices; Igmp Snooping Feature Limitation On Fesx, Fsx, And Sx Devices; Show Interface Brief Command Output - Brocade Communications Systems PowerConnect B-FCXs Release Note

IronView Network Manager (INM) limitation

INM version 3.3.01 and later does not support download of the 07.2.00 router images (SXL07200.bin
and SXR07200.bin). Also, with INM version 03.3.01 and later, it will take approximately six minutes to
upload the Layer 2 switch image (SXS07200.bin) from the FastIron switch to a TFTP server.

ACL Statistics on FGS, FLS, and FWS devices

The FGS, FLS, and FWS do not support the use of traffic policies for ACL statistics only (CLI command
traffic-policy <TPD name> count). However, these models do support the use of traffic policies for ACL
statistics together with rate limiting traffic policies. For more information, refer to "Enabling ACL
statistics with rate limiting traffic policies" in the FastIron Configuration Guide.

IGMP Snooping feature limitation on FESX, FSX, and SX devices

High CPU utilization will occur when IGMP Snooping and PIM/DVMRP routing are enabled
simultaneously on a FESX, FSX, or SX router. With IGMP Snooping and PIM/DVMRP Routing enabled
simultaneously on a given system, IP Multicast data packets received in the snooping VLAN(s) will be
forwarded to client ports via the hardware; however, copies of these packets will also be received and
dropped by the CPU.

Show interface brief command output

If a port name is longer than 5 characters, the port name will be truncated in the output of the show
interface brief command.

ICMP redirect messages

In software release 07.2.00, ICMP redirect messages are disabled by default, whereas in prior releases,
ICMP redirect messages are enabled by default.
If ICMP redirect messages were enabled prior to upgrading to release 07.2.00, you will need to re-
enable this feature after upgrading to 07.2.00. To do so, enter the ip icmp redirect command at the
global CONFIG level of the CLI.
If ICMP redirect messages were disabled prior to upgrading to release 07.2.00, the configuration (no
ip icmp redirect) will be removed from the configuration file after upgrading to 07.2.00, since this
feature is now disabled by default. In this case, ICMP redirect messages will not be sent and no
further action is required.

Enabling and Disabling DHCP-client service on FSX Base Layer 3 devices

By default, DHCP-client service is enabled. If the DHCP-Server is connected to an interface on a FSX Base
L3 device, the interface is assigned a leased IP address. To disable DHCP-client service on an interface on
a FSX Base L3 device, and assign a new IP address, enter the following commands.
Note: In release 07.2.00, the DHCP-client service feature can only be enabled or disabled on a FSX Base
L3 device by performing the following steps.
1. Remove the dynamic IP address assigned to the interface. For example, enter a command such
as the following.
